As we all walk around a little more carefully today, April Fool's Day, one of the places that you can find some great pranks is online.

Google is famous for pulling out all the stops for some of their April Fool's pranks in the past, and this year is no exception. Google Maps has been turned into "Pokemon Challenge", with the famous adventure characters spread throughout the world, and Google Plus is letting you add a celebrity photobomber into your favorite pictures - the one and only David Hasslehoff.

Not to be outdone, plenty of big names are getting in on the fun - from Virgin Airlines (control the temperature from any seat in the plane!) to Bill Clinton goofing on his wife on Twitter.

You can keep an eye on a roundup of April Fool's pranks from around the web here, on BuzzFeed.
